Corrigendum to “The nonlinear S0 Lamb mode in a plate with a linearly-varying thickness” [Ultrasonics 94 (2019) 102–108, (Ultrasonics (2019) 94(102-108) (S0041624X18303688), (10.1016/j.ultras.2018.11.013))

The authors regret the notes in Fig. 2 should be S₁, S₂ and A₂, not as S₂, S₃ and A₃. Some notes in Fig. 2 of the previous version is wrong [1]. The wrong notes (S₂, S₃ and A₃) of the previous version are shown in the following:[Formula presented] Fig. 2. Phase velocity dispersion curves of Lamb modes in aluminum plates with respect to the fd. Symmetric modes are marked red, and asymmetric modes are marked blue. The box region indicates the low frequency region of the S₀ mode. And the corrected version is the following:[Formula presented] Fig. 2. Phase velocity dispersion curves of Lamb modes in aluminum plates with respect to the fd. Symmetric modes are marked red, and asymmetric modes are marked blue. The box region indicates the low frequency region of the S₀ mode. The authors would like to apologise for any inconvenience caused.
